Resize an image to any dimensions
This tool resizes an image to the width and height you choose. Set both dimensions for an exact crop-to-fit result, or just one to scale proportionally with no cropping. Processing happens in your browser — your image is never uploaded anywhere.

Why resize before publishing?
Whether you're resizing a photo for a website or a product image for a marketplace, getting the dimensions right matters — oversized images slow down page loads and waste bandwidth, while an image sized for the wrong platform can get stretched, cropped unexpectedly, or rejected outright. Resizing to the dimensions a platform actually expects avoids both problems.
How it works
Step 1
Upload
Pick any JPEG, PNG, or WebP file. It stays on your device.
Step 2
Resize
Enter a width and height, or pick a preset — the tool crops or scales accordingly.
Step 3
Download
Save the resized image straight from your browser.
Frequently asked questions
- Does this upload my image to a server?
- No. All resizing happens locally in your browser using your device's own processing power. The image never leaves your computer or phone.
- Does resizing crop my image?
- Only if you set both width and height — the tool then crops from the center to fill that exact size. If you leave one field blank, the image scales proportionally with no cropping.
- What image formats are supported?
- You can resize JPEG, PNG, and WebP files, and choose which format to output.
- Can I resize without cropping?
- Yes — leave either the width or height field blank and the tool scales the image proportionally to fit the one dimension you specified.
- Is there a limit on how many times I can use this?
- No. There's no account and no usage limit — resize as many images as you need.
- Is PublishFit free to use?
- Yes. There's no account, no subscription, and no limit on how many images you can resize — PublishFit is free to use, on this tool and every other one on the site.
- Can I use this on my phone?
- Yes. PublishFit works in any modern mobile browser — tap to upload a photo from your camera roll or files, and the resized image downloads straight to your phone.
